Highest temperature in Tokyo on July 14?

Platform comparison

Market context

On 14 July 2026, the highest temperature recorded at Tokyo Haneda Airport Station will determine which range this market resolves to. The settlement window closes at 12:00 UTC on that date, with historical temperature data from Weather Underground serving as the official source. Tokyo's summer climate typically produces daily highs between 30–35°C in mid-July, though heat waves can push readings several degrees higher. The 0% crowd probability suggests traders currently see minimal conviction in any specific outcome, reflecting the inherent difficulty of forecasting weather nine months in advance.

Historical July temperatures at Haneda provide a baseline for calibration. Between 2015 and 2024, the station recorded July highs ranging from 28°C to 37.5°C, with most years clustering around 32–34°C. Extreme heat events—such as the 2022 summer when Tokyo experienced multiple days above 35°C—remain within the realm of possibility but are not the statistical norm. The absence of a clear favourite outcome in the current market reflects this distributional uncertainty rather than any data gap.

From a regulatory standpoint, this weather derivative falls outside CFTC jurisdiction as a non-financial contract, whilst German GlüStV rules do not apply to prediction markets settled on objective meteorological data. UK-based traders accessing this market via polymarket-tax.co.uk should note that no KYC requirement applies for positions under £1,500, simplifying entry for retail participants tracking weather-dependent outcomes. Actual settlement depends entirely on Haneda's recorded data; no discretionary interpretation is involved.

FAQ

Do I need to KYC for Polymarket Tax UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
